If you feel stressed at school, what can you do to make yourself happier? Some may eat their favorite food or listen to some music. Others may go for a walk or get some exercise. A new study found another great way to lower students’ stress—playing with dogs.
Scientists studied 105 students between the ages of eight and nine. Thirty-five trained dogs and their trainers also took part in the test. The children were divided into 3 groups. The students in the first group spent 20 minutes with a dog and its trainer. They watched the trained dogs perform and even played with them. They did this twice a week for 4 weeks. The second group spent the same amount of time (时长) doing exercise to relax. The last group did neither of these things.
During this time, the scientists recorded the students’ cortisol levels (皮质醇水平). Cortisol is a stress hormone (激素). The more stressed you feel, the more cortisol you will have in your body. What did the scientists find? Both the second and the third groups showed rises in cortisol levels. The first group, however, showed no big increase. And the children in this group had the lowest cortisol levels right after playing with the dogs.
According to the study, students enjoy playing with dogs, and it helps them become happier. The stress hormone falls over time this way, which is good for students’ health. But here comes the next question: Is 20 minutes of playtime with a dog the best amount of time? Scientists are going to keep working to find out the answer.

【推荐3】Look at your Chinese lunar calendar(农历), and you can find many solar terms on it, such as jingzhe or mangzhong. They are also called jieqi in Chinese.
About 2,000 years ago, Chinese people studied natural changes such as temperature(温度), water and crop growth. They then made 24 solar terms to show the changes in season and weather.
For example, they named the day with the year’s longest daytime as xiazhi. The shortest one is called dongzhi. It is usually snowy around xiaoxue every year. And dahan is the coldest day of the year.
Also, the solar terms help farmers make plans. They are going to sow seeds (播种) when lichun comes. When mangzhong comes, wheat is ripe(成熟的). The harvest time is coming!
Today, the solar terms are still used by Chinese people and they are helpful to our daily life. Did your mom ever tell you “don’t show your feet after hanlu”? You’d better listen to her, because hanlu means the beginning of cold days.

J. K. Rowling is the writer of Harry Potter, which is now one of the best-selling book series in the world.
J. K. Rowling was born in Bristol on July 31st, 1965. She has one sister who is two years younger than her. Both girls loved listening to their father read them stories. They especially loved stories about magical words. Rowling wrote her first story called Rabbit, at the age of six.
After she graduated (毕业) from university, Rowling worked as a translator in London. During this time on a long train trip in the summer of 1990, the idea of a boy who had magic but doesn’t know it came to her. In 1992, Rowling began to teach English. She lived with her baby daughter, Jessica, and spent much time finishing the first Harry Potter book for young readers. It came out in June, 1997. To her surprise, the book was very greatly successful. The film came out in November, 2001. Now Harry Potter is popular with people of all ages and about sixty million books have been sold in 200 countries and areas.
Why has the series been such a great success? There are a few reasons. Many other magical stories take place in faraway lands or in the past or in the future. But Harry lives in Modern England. He is also a very normal boy: polite, friendly, brave and clever. So, when other children read about Harry, they can imagine being like him.
J. K. Rowling is very happy with the success, and she is writing full time and is really enjoying life. She says she will go on living a normal life with her daughter and go on writing children’s books.
